DE1110046B - Dry shaver with removable cutting head - Google Patents

Description

In the case of a dry shaver, the cutting head should be removable. For this purpose it is known on the cutting head at least one cutting plate provided with openings and further at least one Provide pin with an incision for attaching the head to the device and in this incision in the attached state to store an elongated spring that is attached to the housing of the device.

Such a locking device makes it possible to remove the cutting head and put it back on his Place to bring.

Both an operating slide and a push-button lock are known as a latching device. These known devices are not sufficiently secure. The slide lock requires a special one Actuation, is subject to contamination and requires manual actuation, which is avoided should be, and with a pressure ball arrangement, the small spring used here loses in the course the elasticity of time; moreover, it can only accommodate tolerances to a limited extent. Are unsatisfactory also snap fasteners with spring wire for attaching parts of dry razors. All These known solutions compared to an improvement is to be created that is characterized by large Simplicity and characterized by permanent, sufficient and reliably acting resilience. this will achieved according to the invention in the aforementioned type of dry shaving devices, that the spring (s) is (are) in the cut hair collecting space behind the cutting plate and this Spring (s) is (are) fastened with one end to the floor of the room in such a way that they fit in there Piece at the bottom extends (extend), while the other end in the incision of the pin (s) is stored and extends further up to the open boundary wall of the cut hair collecting space (extend).

If the device is provided with two cutting plates, each with a rotatably arranged cutting element, which is equipped with its drive axle is coupled, which is guided through the bottom of the cut hair collection chamber, so the solution according to the invention is implemented here in such a way that between the axes of the two cutting members two wire or leaf springs are arranged side by side, with their on the ground ends attached to the cut hair collection chamber are on opposite sides and each Cutting head is provided with a pin and the incisions on opposite sides of the pins are provided.

Exemplary embodiment, the invention is explained in more detail:

Fig. 1 shows a section transversely through the housing of a dry shaver with a removable Cutting head with two cutting plates;

FIG. 2 shows a plan view of the housing according to FIG. 1, with the cutting head removed from the housing is removed.

The housing 1 of the dry shaver is provided with a removable cutting head 2 in which there are two perforated cutting tips 3 in a known manner. The cutting head 2 has two Pins 4 provided which have an incision 5 at their free ends, of which only the incision of the in the drawing on the left illustrated pin 4 is visible · From the pin 5 shown on the right the incision 5 is on the back away from the viewer · The pins 4 extend up to a cut hair collection chamber 6 which is formed between the housing 1 and the cutting head 2 through two drive axles 8 are passed through the bottom 7 of this chamber 6, and between them Axes are two wire springs 9 and 10 next to each other. The ends 11 and 12 are at opposite ends Sides attached to the bottom 7 of the cut hair collection chamber 6 by means of a screw 13 and 14, respectively.

In the unsecured state of the cutting head 2, the springs 9 and 10 extend over the Bottom 7 of the cut hair collection chamber. The free

Ends 20 and 21 of the springs 9 and 10 extend to the wall 22 of this chamber 6, the is formed locally by flaps that can be opened. In Fig. 2, these flaps are in Illustrates open state. With such an arrangement, it is particularly easy to attach or to loosen the cutting head 2, the free ends 20 and 21 in the incisions 5 of the Pins 4 in or out of these.
